Investigations are depicted in Table 1. Child underwent portoenterostomy after 1 week. On table, it was noted that child had atretic gall bladder with malrotation with Meckel’s diverticulum and megaureter.

Question :
What are the anatomical malformations associated with biliary atresia_?
Expert Opinion :
Biliary atresia is characterized by obliteration or discontinuity of the extra hepatic biliary system, resulting in obstruction to bile flow. There are 3 types of biliary atresia:
Type 1: Atresia restricted to common bile duct
Type 2: Atresia of the common hepatic duct
Type 3: Atresia of the right and left hepatic duct
Patients with biliary atresia generally pass acholic stools with onset at about 2 weeks of life. They are average birth weight. They have firm hepatomegaly. {1} There is a female predominance. They may have associated polysplenia syndrome, heterotaxy, and reverse rotation of intestine, in isolation or in various combinations and intra-abdominal vascular anomalies. {2} In addition, malrotation, Meckel’s diverticulum and jejunal atresia have also been reported with biliary atresia. {3} Biliary atreisa in association with other congenital structural anomalies may have a poor prognosis. These patients have poor bile secretion after hepatic portoenterostomy. {4}
